I had a thyroidectomy for nodules , the gland was completely removed 41 years ago. I have never had a problem with regulating the thyroid dosage untill recently for the past six months I have been having my TSH level checked every six weeks and levothyroxine adjusted,with each test it remains either too high or too low. My blood work also shows anemia, and one test with a low white blood cell count. I have had both iron and B12 levels tested and iron and B12 are at the low end of normal range. Internal bleeding has been ruled out.
I am 65 years old. Could the anemia be pernicious anemia? Do you have any recommendations.
